Travis build error: sass requires Ruby version >= 2.0.0

Question

所以出于某种原因，我的 Travis 构建失败并出现以下错误：

10.33s$ gem install sass
Fetching: rb-fsevent-0.10.2.gem (100%)
Successfully installed rb-fsevent-0.10.2
Fetching: ffi-1.9.18.gem (100%)
Building native extensions.  This could take a while...
Successfully installed ffi-1.9.18

Successfully installed sass-listen-4.0.0
Fetching: sass-3.5.1.gem (100%)
ERROR:  Error installing sass:
    sass requires Ruby version >= 2.0.0.
The command "gem install sass" failed and exited with 1 during .

```

我的travis.yml文件如下：

language: node_js
node_js:
    - 6
before_install:
    - gem install sass
    - gem install scss-lint
    - npm install -g grunt-cli 
install: 
    - npm install
before_script: 
    - grunt theme

```

我什至尝试指定一个大于 2 的 Ruby 版本，但 "sass requires Ruby version >= 2.0.0" 的错误仍然存在：

language: node_js
node_js:
    - 6
before_install:
    - gem update --system 2.1.11
    - gem --version
    - gem install sass
    - gem install scss-lint
    - npm install -g grunt-cli 
 install: 
    - npm install
before_script: 
    - grunt theme

我有另一个项目有一个或多或少相同的 travis.yml 文件，所以我这辈子都弄不明白哪里出了问题。

使用 rvm 这样的包管理器安装 ruby 2.0 及更高版本。官方 ruby 存储库安装 v1.9，所以这就是您收到错误的原因。下面的命令可用于此。

rvm install 2.x
